The E92 CSL is what you see in the M3 GTS and M3 CRT. To make a CSL requires board approval. BMW M GmbH developed an E92 CLS in '09 and the board did not green light the project.

Instead what M did was build cars via BMW Individual (Does not need board approval as they were built at M in Garching) using the R&D that was to be the E92 M3 CSL. That is the real story...

The final hurrah of the E92 will be market specific and the M Performance accessories will play a key roll as will BMW Individual Paint. There has been no significant development on the dead E9X chassis as all R&D focus is on the F80, the next X5M, as well as the M6GC which will see S63tü Phase II.

M is also key in developing a lot of other product (M Sport kits, suspension, M Performance Automobiles, supporting some of Alpina) so their hands are full with enough things for the future let alone a nostalgia project.

Let's not forget that the "competion package" is really all the US saw with the E46 generation so why expect anything different? And Europe has already seen two CSL based limited editions... the car is already where it needs to be at this point in its life cycle.
